A viral infection does not always cause disease. A viral infection simply involves viral replication in the host, but disease is the damage caused by viral multiplication. [5] An individual who has a viral infection but does not display disease symptoms is known as a carrier. [17] Mechanisms by which viruses cause damage and disease to host cells

The Journal of Infection is the official publication of the British Infection Association (formerly the British Infection Society and the British Society for the Study of Infection). Since 2006, the editor-in-chief has been Robert C. Read, an infectious disease physician and Chair of Infectious Diseases at the University of Southampton , [ 1 ...
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. [1] Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. [2] [3] Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity.
GPGV is a positive single-stranded RNA virus, [1] meaning that the genome of the virus is made up of RNA nucleotides. While Giampetruzzi and her colleagues found the genome to have similarities to the marafiviruses Grapevine Syrah virus-1 and Grapevine Rupestris vein feathering virus, it was found to be more similar to the Trichovirus genus.
Diagram of a NPV lifecycle A dead caterpillar infected by NPV. The baculovirus lifecycle involves two distinct forms of virus. Occlusion-derived virus (ODV) is present in a protein matrix (polyhedrin or granulin) and is responsible for the primary infection of the host, while the budded virus (BV) is released from the infected host cells later during the secondary infection.
Turnip yellow mosaic virus crystals grown on Earth (left) and in outer space under microgravity conditions (right). [1] Turnip yellow mosaic virus (TYMV) is an isometric Tymovirus of the family Tymoviridae. Its host range is confined almost entirely to plants in the genus Brassica in western Europe, which includes cabbages, cauliflower and ...
Donald L. D. Caspar (January 8, 1927 – November 27, 2021) was an American structural biologist (the very term he coined) known for his works on the structures of biological molecules, particularly of the tobacco mosaic virus.
